Answer:
a. 76 b. 52
Step-by-step explanation:
The perimeter of a rectangle is the sum of its four sides.
Now all rectangles have a width and a length.
To find the perimeter it is 2 width + 2 length or 2W +2L.
So if the Perimeter P = 344 and Width W = 76 and P = 2W + 2L
Then...
2(76) + 2L = 344 multiply 2 and 76
2L + 152 = 344 subtract 152 from both sides
2L = 192 divide both sides by 2
L = 96
The length is 96.
The equation of an area of a rectangle is A or area = width x length or W x L
So the equation is A = W x L
If the area is 4732 and the length is 91 then
91W = 4732 divide both sides by 91
W = 52
The width is 52.

Answer: 11.46
Step-by-step explanation:
Formula for calculating the length of an arc is theta/360 ×2Πr. Where;
length of the arc (L) = 9
Theta= 45°
L = theta/360 × 2Πr
9 = 45/360× 2Πr
9 = 1/8 × 2Πr
9 = Πr/4
Πr = 36
r = 36/Π
r = 11.46
Substituting we have,
9 = r × 45°
r = 9/45
